More than 4,500 pounds of chicken nuggets are being recalled because they may contain “extraneous plastic materials.”

The chicken nuggets were made by Perdue Foods LLC for Applegate Farms, according to the United States Department of Agriculture. The recall was announced Saturday, March 5, 2016.

The recalled nuggets were 8-oz. boxes containing 18 pieces of “Applegate Naturals Chicken Nuggets” with a best by date of 09/27/2016, the USDA said. Their establishment number is “P-2617” which is inside the USDA mark of inspection. The nuggets were made on September 28, 2015.

The Food Safety and Inspection Service confirmed that the nuggets could be contaminated with plastic materials. The problem was discovered when customers started complaining about “small, solid, clear plastic inside the Applegate Naturals Chicken Nuggets.”

“There have been no confirmed reports of adverse reactions due to consumption of these products,” said the FSIS statement. “Anyone concerned about an injury or illness should contact a healthcare provider.”

The nuggets were shipped to distributors in Florida, Georgia, Indiana, Massachusetts, Pennsylvania, New York, and Texas, the statement said.

If you have these nuggets, you are urged not to eat them, the statement said. They should be thrown away or returned to wherever you bought them. Any questions about the recall can be directed to Applegate Consumer Relations at 1-866-587-5858.

This is considered a Class I recall, which means there is a “reasonable probability that the use of the product will cause serious, adverse health consequences or death,” according to the USDA Recall Classifications.
